Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

I'm failing the random test cases and I can't figure out what the issue is. For example, on Input array: [27,13,12,29,53,41,24,20,19,40,44,31,5,36,25,50,15,22,30,26,17,21,11,32,38,43,46,34,18,14,39,35,3,51,33]
I get the following failure message:
Expected: '', instead got: '3, 5, 11-15, 17-22, 24-27, 29-36, 38-41, 43-44, 46, 50-51, 53'
Why is it expecting an empty string? What am I missing?
